In the following, an example of the operation of the electronic device X1 is described in the case of transmitting the pushing sensation to the user of the tactile transmission, electronic device X1 is other than pressing feeling, for example, tracing feeling, touch feeling, etc. it is of course to be applied to a case of transmitting various tactile.

As shown in FIG. 8, the user, when pressing the touch panel 4 through the operation unit 6, the vibrating body 7 detects a pressing load to the operation section 6 (Op1). Here will be described a load detection function of the vibrating body 7. That is, the user, when pressing the touch panel 4 through the operation unit 6, the operation unit 6 is bent downward. When the operating unit 6 is bent downward, the vibrating body 7 also curved downward. That is, in response to the pressing load to the operation portion 6, a bending amount of the vibration member 7 is displaced. In the present embodiment, the vibrating body 7, since a piezoelectric element can be converted into a voltage corresponding to a curve amount. As a result, it is possible to detect the pressing load to the operation section 6 by the vibrating body 7. In the example described above, which realizes the load detection function in the vibrating body 7 is not limited thereto, for example, may be implemented by a load sensor such as a strain sensor.

The tactile transmission driver, not shown, determines the input operation by the user, when the push operation to the input object displayed on the display screen, whether the pressure load detected by Op1 is equal to or higher than the threshold to (Op2). Incidentally, the tactile transmission driver, for example, on the FPC connected to the touch panel 4 (Flexible Printed Circuit), it is provided with a touch panel driver for controlling the touch panel 4.

The tactile transmission driver, if it is determined that the pressing load detected by Op1 is equal to or higher than the threshold (YES at Op2), expanding and contracting movement of the vibrating body 7 in the short side direction of the operation unit 6 (Op3). By vibrating body 7 which is telescopic movement operating portion 6 and the touch panel 4 is bent vertically vibrated at Op3 (Op4). Thus, the pressing sensation is transmitted to the user of pressing the touch panel 4 through the operation unit 6. On the other hand, the tactile transmission driver, if it is determined that the pressing load detected by Op1 is smaller than the threshold value (NO in Op2), and terminates the process of FIG.

Thus, the electronic device X1 described above, while ensuring a certain degree of dust-proof and waterproof, it is possible to transmit a sufficient tactile to the user.

Therefore, by expansion and contraction of the vibrating body 7, when it is intended to bend the vibrating operation section 6 in the vertical direction, a second portion 80b positioned at the four corners 32a ~ 32d of the frame 32 becomes a fulcrum, it is possible to sufficiently curved vibrating the operating unit 6 in the vertical direction. Therefore, in the electronic device X2, as compared with the electronic device X1, it is possible to transmit a sufficient tactile to the user.

As described above, in the electronic device X2, while ensuring a certain degree of dust-proof and waterproof, it is possible to transmit a sufficient tactile to the user.
